Install spoofing, also known as SDK spoofing, is a type of ad fraud where attackers manipulate data to create fake app installations, misleading advertisers into believing their ads have driven genuine user downloads. This type of fraud exploits the software development kits (SDKs) used by app developers to track and attribute installs.

Fraudsters achieve install spoofing by intercepting and faking the data that apps send to attribution platforms. They simulate app installs and user engagement without the app actually being installed or used by real users. This fraudulent activity often involves generating fake device IDs, clicks, and installs, making it appear as though the ads are performing well and driving high volumes of downloads.

Install spoofing significantly impacts advertisers by wasting their ad budgets on non-existent users, skewing campaign performance data, and leading to incorrect conclusions about ad effectiveness. It can also distort key performance indicators (KPIs) and hinder accurate measurement and optimization of marketing strategies.

To combat install spoofing, advertisers and app developers employ various techniques, such as implementing robust SDK security measures, using advanced fraud detection tools, and analyzing install patterns for anomalies. These efforts help ensure that reported app installs are genuine and attributable to legitimate user interactions.
